GBOL III: Dark Taxa

The BMBF-funded GBOL, the German Barcode of Life initiative, has been run successfully over the last eight years. It delivered an operative DNA barcode reference library for German animals, fungi and plants. However, a significant proportion of insect taxa has so far been excluded from GBOL and merely all biodiversity research, because no or only very insufficient expertise and information are available that allow to get a grip on them. They are called “Dark Taxa”.

Afrotropical Ceraphronoidea

The parasitoid wasp superfamily Ceraphronoidea - with two families Ceraphronidae and Megaspilidae - is considered one of the less species-rich superfamilies of the often megadiverse parasitoid wasps (only ca. 600 species described worldwide). However, we hypothesize that the species diversity of the group is severely underestimated. To shed some light on the true diversity of Ceraphronoidea, we study the species of selected localities of subsaharan Africa, mostly from Kenya and Tanzania.

The chalcidoid megaradiation

Chalcidoidea are one of the species-rich groups of parasitoid waps. They show a remarkable diversity in outer appearance and life history and can be found often in high abundance in nearly all terrestrial ecosystems around the world. The evolution of the Chalcidoidea, however, is still unsuffficiently understood. Also, the current classification is not based on natural groups and needs to be revised.

Establishing a standardized and universally applicable set of nuclear-encoded markers for genome-wide multi-locus species delimitation of metazoans

Methods for delimiting species based on multi-gene nucleotide information are well established and provide the means to complement the classical COI barcoding approach, whose limitations are well known. Our research project aims at establishing a standardized set of single-copy nuclear-encoded markers for genome-wide multi-locus species delimitation by exploiting comparative genomic data and applying target DNA enrichment. Candidate markers are so-called Universal Single-Copy Orthologs (USCOs).

Plant-pollinator networks in agro-ecosystems

Pollination is crucial for maintaining angiosperm biodiversity and represents one of the most important ecosystem services. With the increasing threats of massive insect decline, studying pollination and associated networks has become more important than ever. In this study, we target the plant-pollinator networks of two important crops (caraway and apple) using a combination of traditional methods with DNA barcoding and metabarcoding.

The phylogeny and evolution of Torymus

Within the genus Torymus (Chalcidoidea: Torymidae), very diverse parasitoid strategies and adaptations to its hosts have evolved. Its larvae are ectoparasitoids and attack mostly larvae of various gall wasps (Hymenoptera: Cynipidae) and gall midges (Cecidomyiidae). We study the coevolution of the genus Torymus and its hosts and target the question what kind of host shifts occurred during the evolution of the group. For this, we reconstruct the first phylogenomic tree for the the genus Torymus.

1KITE: The evolution of the insects

Insects are one of the most species-rich groups of metazoan organisms. They play a pivotal role in most non-marine ecosystems and many insect species are of enormous economical and medical importance. Unraveling the evolution of insects is essential for understanding how life in terrestrial and limnic environments evolved. The 1KITE (1K Insect Transcriptome Evolution) project aims to study the transcriptomes (that is the entirety of expressed genes) of 1,000 insect species encompassing all recognized insect orders. For each species, so-called ESTs (Expressed Sequence Tags) will be produced…

We try to reconstruct a robust backbone tree of holometabolous insects based on extensive transcriptome/genome data. With our transcriptome data we cover all orders within these group of insects and optimize the procedures of tree inference based on these data. Additionally, Rolf Beutel's group is providing extensive 3D morphological data of head, thorax and abdominal structures. Together we are working on the most extensive morphological and molecular data addressing the above mentioned phylogenetic questions. Within this project we have also started to specifically address the "Strepsiptera…
